Hello, I was downloading 3 movies via sabnzbd (~5GB each), after awhile I noticed the system wasn't responding as much, RhythmBox wasn't playing anymore, sabnzbd wasn't making progress and my broswer also was slowing down a bit. I then decided to restart thinking it would solve what ever problems sabnzbd brought along, when I did that it didn't reboot it just logged me out, I couldn't log back in, it would accept my password and username but after that nothing would happen, I then hard powered it off, on start-up it wouldn't get past the "mounting local filesystems" part of the boot process, it would just print DMA errors and more. I'm running PassMark's DiskCheckup on both my disks, on the first the quick self check completes quickly without error, but the second drive doesn't get past 10% (starts on 10%) and shows "The last self-test routine completed with a failure of the read element." I was wondering is my disk 100% gone? or is the some chance of getting my RAID0 data off? although 90% is easily replaceable (movies). Thanks. (I'll reply later with the details of the error messages displayed during boot.)
